This paper presents our on-going research at bringing the state-of-the-art in vision and robotics technologies to enhance the emerging minimally invasive surgery, in particular the laparoscopic surgical procedure. A framework that utilizes intelligent visual modeling, recognition, and serving capabilities for assisting the surgeon in maneuvering the scope (camera) in laparoscopy is proposed. Th...

We have attached ACT-R to the Air Force Research Laboratory’s (AFRL’s) Uninhabited Air Vehicle (UAV) Synthetic Task Environment (STE). The UAV STE is a high fidelity simulation of the Predator RQ1A UAV with built in basic maneuvering, landing, and reconnaissance tasks and data collection capabilities. The UAV STE’s design and capabilities are described in detail in Schreiber, Lyon, Martin, and ...

Unmanned small autonomous helicopters can perform aggressive maneuvers that will be useful for operations in challenging conditions. This paper presents an analysis of the pilot’s execution of aggressive maneuvers from flight test data, collected on an instrumented small-scale acrobatic helicopter. A full-envelope nonlinear dynamic model of the helicopter was developed and validated for aggress...

Since future air combat missions will involve both manned and unmanned aircraft, the primary motivation for this research is to enable unmanned aircraft with intelligent maneuvering capabilities. During air combat maneuvering, pilots use their knowledge and experience of maneuvering strategies and tactics to determine the best course of action. As a result, we try to capture these aspects using...

This paper discusses the maneuvering control algorithm based on all-wheel independent driving and steering control techniques for special purpose 6WD/WS vehicles. The maneuvering control algorithms considering superior dynamic characteristics of high power in-wheel motors and independent steering system are designed to perform driving and steering control, vehicle stability control, and fault t...

Maneuvering targets are di cult to track for the Kalman lter since the target model of tracking lter might not t the real target trajectory and the statistical characteristics of the target maneuver are unknown in advance. In order to track such a heavy maneuvering target, the estimation of the target turndirection is necessary. The two-stage estimator using advanced circular prediction which c...

The failure to detect anomalies and maneuvering of the orbits of navigation satellite sensors will deteriorate the performance of positioning and orbit determination. Motivated by the influence of the frequent maneuvering of BDS GEO and IGSO satellites, this paper analyzes the limitations of existing methods, where BDS orbit maneuvering and anomalies can be detected, and develops a method to so...

Maritime transport has been playing a decisive role in global trade. Its contribution to the air pollution of the sea and coastal areas has been widely recognized. The air pollutant emission inventories of several harbors in China have already been established. However, the emission factors of local ships have not been addressed comprehensively, and thus are lacking from the emission inventorie...

A detection scheme is presented for maneuvering affordance in noisy imagery. By introducing a mental maneuvering process within an intentional coordinate system, image features are assumed to be represented in terms of directional Fourier images. The detectability of affordance patterns has been verified through experimental studies.
